You would have seen it fall out most likely. The stock is pretty useless, if you are really worried about it just buy an aftermarket, I now wish I would not have sold my hyperpro since i decided to keep my bike. Its a great SD

That frame boss is for the steering damper bracket. The bracket is held to the frame with two bolts and to the radiator bracket with one bolt. The steering damper is also held to the lower triple with a bolt. The Damper is held to the bracket with one bolts.

That's five bolts on the assembly, four of which hold it to the bike. Highly unlike that they fell out at the same time
